TO ALLMWHOM IT MAY CONCERN:

Be it known that I, A'UGUST ROOS, of the city and State-of New York,have invented, made, and. applied to use a ecrtain new and usefulimprovementin Rectit'ying Spirits; and I do hereby declare the followingto be a full, clear, and exact description of the said invention,reference being had lto, the annexed drawing, making part of thisspecification, wl1erein Figure 1 is a section vertically of my improvedtestifying apparatus, and

Figure 2 isa view of the rectifying tube broken open and in perspective.

Similar letters denote the same parts.

Inthe distillation and recticationof alcohol -and spirit-s astill, a,has been used, heated by a steam pipe, b, the vapor rising through therectifying column c, having caps d over the vapor-tubes to direct suchvapor through the liquid upon the successive diaphragms, -and the liquidhas been returned by the overflow pipes e to the still, while the vaporshave passed oil either to a second rectifying column or to a condenser.

In almost all the condensers heretofore employed the vapors` alternatelyascend and descend, thereby coming into contact with the en ipyrcumaticoils' that condense before the spirit, and by that contact cause thespirit to receive or retain the taste andsniell of such oils, or elsethey are condensed and passaway with the alcohol or high wines.

YThe object of my said invention is to more perfectly separate theempyreumatic oils and cause them to pass away in the opposite directionto. the spirit, so that the objectionable smell and taste are removed asquickly as possible from the vapors, and donot come in contact with thealcohol as' it is condensed.

In the drawing the vapors pass from the column c, through the pipeg,into a double case, the vapors being in the space between the cylindersL and z'. This space is divided by segmental rings c,(see' Hg. 2,)placed-alter-4 nately so that the vapors are checked and4 cornpelled totravel zigzag, and lthereby th'e condensation is much more thorough oftheriinpurities, the temperature being maintained by the water bath Z,in which such column is placed, so that not-hing but spiritvapors willpass by the pipe m into the refrigerator@ The condensed vapors pass fromthe case 7L z'bacl; into the coliimn e, by the pipe o, or, if desired,may be led back to the still through a pipeand cock, shown at o', thatconnects with thepipel p. The refrigerator n is formed with a case thatis double, with segmentalA rings 7c, the saine as in the case t a', andthe condensed spirit passes od" by the tube t', into which a test-glassmay be'inserted.

This invention may be used for condensing the spirit in any part of therectification or distillation of the same. A

What I claim, and desire to secure by Letters Patent, is

The rectifying condenser formed of the canse lt 1.',- with the segmentalrings placed alternately, to arrest the vapors as' they pass up throughsaid condenser, as and for' the purposes set forth.

lIn witness whereof I have hereunto set my signature this 12th day ofJune, 1867.
